Whoa, LOL, The U.S, Open Tennis Championships 2016, Check It Out.

Mother Nature forced the USTA’s hand in building the roof. From 2008-12, five men’s finals at the Open were postponed a day to Monday due to rainouts. In 2011, four rounds of tennis had to be played over four days as organizers scrambled to reschedule matches. Fans were left unhappy with ticket situations and players lamented the shortened recovery time. The USTA had already commissioned several roof studies, but repeated rainouts spurred the group to find a permanent solution. Its cost is part of a larger $500 million facelift on tennis center grounds.

The U.S. Open is now the third Grand Slam event to boast a roof. Wimbledon and the Australian Open previously added theirs in recent years, and the French Open intends to build one over Roland Garros in the near future.
